During May 2025, Luo refactored the prompt configuration system for the knownsec/aipyapp repository, focusing on improving maintainability and user prompt quality. Luo migrated the MCP prompt content from a Python source file to a TOML configuration, enabling a more flexible, configuration-driven approach to prompt management. This change allowed for faster iteration and reduced the risk of regressions from code changes, while preserving the existing task decomposition behavior. Luo’s work leveraged Python programming, configuration management, and AI development skills to optimize prompt wording and ensure traceability through commit history, resulting in a more stable and maintainable prompt system overall.
